50% of what number is 60?

Answer 1

120

Explanation:

You want to find a number such that 50% of it is 60, using the formula R×B = A.

Percent relation

An amount is found by multiplying the rate by the base. That is described by the formula ...

R × B = A

Here, we're given the amount and the rate, and we want to find the base. We can fill in the given numbers and solve for B.

50% × B = 60

B = 60/0.50 . . . . . . divide by the rate

B = 120 . . . . . . . simplify

50% of 120 is 60.
